Genesis of rare molecules using light-induced reactions of matrix-isolated tetrazoles
Publication date: March 2014 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews, Volume 18 Author(s): L.M.T. Frija , M.L.S. Cristiano , A. Gómez-Zavaglia , I. Reva , R. Fausto Tetrazoles exhibit a very rich photochemistry, strongly influenced by the nature of substituents in the tetrazolic ring. Photolysis of representative tetrazoles trapped in a rigid environment of solidified noble gases at cryogenic temperatures (usually argon at 10–15K) results in photofragmentation of the monomeric species with a wide range of exit channels. Since the obtained fragments are generally confined to t...

Computational studies of charge transfer in organic solar photovoltaic cells: A review
Publication date: March 2014 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews, Volume 18 Author(s): Neha Agnihotri Photoinduced charge transfer (CT) is a fundamental process that determines the overall energy conversion efficiency of organic solar photovoltaic cells (OPVs). This review focuses on the advantages and pitfalls of theoretical/computational methods available to describe CT excitations in donor–acceptor (D–A) complexes. Studies of porphyrin–fullerene constructs as model D–A systems will be used to illustrate progress in this area. (Source: Journal of Photochemistry and Pho...

Carbon nanotube-based fluorescence sensors
Publication date: June 2014 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews, Volume 19 Author(s): Chun Li , Gaoquan Shi The one-dimensional π-conjugated structure endows carbon nanotube (CNT) with large specific surface area and excellent photophysical properties, thus providing a unique platform for the development of chemo- and biosensors based on optical signal output. Although CNT acts as an optical signal transducer, it does not own any intrinsic ability for the selective binding and recognition of analytes. Thus, hybridization of CNTs with functional components that specifically rec...

Photochemical reactions applied to the synthesis of helicenes and helicene-like compounds
Publication date: June 2014 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews, Volume 19 Author(s): Norbert Hoffmann Helicenes are composed of ortho annellated benzene moieties. Similar compounds contain heterocyclic or dihydrobenzene rings or smaller rings such as cyclopentadiene or cyclobutadiene (as part of benzocyclobutene units). The present article resumes photochemical reactions used for the preparation of these compounds. A very important and generally applicable reaction used for the synthesis of helicenes and helicene-like compounds is the photocyclization of stilbene subunits follo...

Electron injection efficiency in dye-sensitized solar cells
We present difficulties associated with obtaining Φ inj by means of such techniques, and we propose nanosecond time-resolved transient absorption spectroscopy as a reliable method. Then, Φ inj values obtained are summarized. Factors limiting Φ inj are discussed from the perspective of free energy changes for electron injection, the molecular structure of sensitizer dyes on the surface, and the presence of fast charge recombination pathways.
